When I started data mining the StackOverflow database, I found a surprising number of users had set their birthday in a way that made them 89 years old.
I blogged about it and gave a full list of the 89-year-old users, and here's a few:
- deuseldorf - Age 89
- Coding the Wheel - Age 89
- Keng - Age 89
- Will Dean - Age 89
- kokos - Age 89
- ColinYounger - Age 89
- Lars Truijens - Age 89
- dydx - Age 89
- Confused Computer Guy - Age 89
And it's not like it was an even distribution - there were much less 80-87 year old users, and no 90 year old users. I'm guessing these users picked a date 89 years ago (so, somewhere about 1920) that has some special significance, but I can't figure out what it might be.
What's so special about year 1920?
